Hi Haomai,
Hmm, one other thing: I'm testing the fix in wip-8701 and it is tripping
over the KeyValueStore test. This
./ceph_test_objectstore --gtest_filter=ObjectStore/StoreTest.BigRGWObjectName/1
fails with

NOTE: a copy of the executable, or `objdump -rdS <executable>` is needed to interpret this.
It's a new test (long file names and collection_move) that addresses an
issue with the FileStore, but KeyValueStore doesn't seem to like it
either...
Thanks!
